Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81022, here are decompositions:

3 + 81019 = 81022
5 + 81017 = 81022
59 + 80963 = 81022
89 + 80933 = 81022
113 + 80909 = 81022
173 + 80849 = 81022
191 + 80831 = 81022
233 + 80789 = 81022

Showing the first eight; more decompositions exist.
